Maintenance of pumped storage plants. Pumped Storage plants are among the most sophisticated hydro plants that civil engineers are required to build, and the time required to plan and design a scheme ensures that relatively few design engineers are involved with the implementation of more than one such project in their professional career.
The hydrologic design basis for a pumped storage facility, as for a conventional hydro project, is mainly concerned with determining the appropriate Inflow Design Flood (IDF) and Probable Maximum Flood (PMF) for the project. Guidance on selecting the IDF and PMF can be found in Chapters 2 and 8 of the FERC''s Engineering Guidelines.
